2 SAFETY PRECAUTIONS Fireplaces may be set up only in rooms or areas with no risk of danger due to their location, structure or intended use. Working on the stove Working with electronics Installation, commissioning, servicing and maintenance works on the product may be carried out only by an authorized stove-fitter. Safety and efficiency of the system depend on this! Switch off the emergency switch or circuit breaker, and secure them against switching on again. Fireplaces with external air supply are not independent from room air supply and must be considered and designed as roomsealed fireplaces. In connection with a ventilation or extraction system, we recommend the use of a negative pressure safety device USA (Art.No.: 11600.1). Installation must be carried out by an authorized stove-fitter, because safety and efficiency of the system depend mostly on proper installation of the product. All valid stove fitting rules and regulations of building law must be observed and followed. Make sure to instruct the owner or user about the functions and controls of the system and possibly installed safety devices. Fireplaces must be built to ensure safe operation and fire safety in order to eliminate possible risks and unacceptable loads. They have to be ready for use over an adequate period of time. Make sure to instruct the owner or user about the functions and controls of the system and possibly installed safety devices. Remember to use only genuine replacement parts. Stoves with water boilers are ready for use only with a fully functional boiler section. 4 General Indications Installation of a Brunner fireplace 2017 Brunner GmbH
3 COMBUSTION AIR Sufficient combustion air supply A fireplace may be installed only in rooms, where sufficient combustion air supply is guaranteed. Normal operation requires sufficient air supply using a separate combustion air connection for the fireplace. Sufficient combustion air supply is present, when by natural means or using technical equipment a combustion air volume of 12,5 m 3 per 1 kg fuel throughput can stream into a room with wood-burning fireplace over a period of 1 hour at calculated negative pressure below 0,04 mbar (4 Pa) against outside air pressure. This is equivalent to a speculative heating power (PLF) of 8 kw per 1 kg fuel throughput. When other fireplaces are in operation in the same room or different rooms included in one room combination, these fireplaces require at least 1.6 m 3 of combustion air per hour for each kw of their total rated heating power. When a room combination contains only a small volume of air and the building is relatively air-tight, a separate combustion air supply from outdoors is required. Combustion air supply is ensured in rooms with at least one window or one door which can be opened to outside of the building, or when these rooms are directly connected or interconnected with other rooms of such type. Rooms considered as directly connected or interconnected, can be only parts of one apartment or one facility of other kind. Particular attention to combustion air supply is to be paid, when exhaust fans and other heat generators in the same room combination are operated, or when multiple heating devices are connected to one single chimney. Ventilation systems in this room combination cannot create negative pressure, which could affect the functioning of the fireplace. Exhaust ventilation systems operating in the same room or room combination together with fireplaces, can cause many problems. When the fireplace allows for open door use, the volume of required combustion air is significantly increased (see technical data). Combustion air ducts If external combustion air supply is necessary, it must be connected directly to the air supply connecting piece of the fireplace, to prevent possible air drafts. The combustion air duct must have sufficient cross-section. It must be laid using the shortest way and without unnecessary bends, to reduce flow resistance. Combustion air duct dimensioning must be according to EN13884; flow resistance has to be estimated by calculation and must be taken into account! Components of combustion air duct must be made of non-flammable, dimensionally stable and abrasion resistant materials (DIN 4102 A1 or Class A1(B2) according to DIN EN 13501-1); they must ensure tightness und be accessible for inspection and cleaning. Thermal insulation is necessary from the fire-protection point of view, if air temperatures >85 C are possible. Temperatures below dew point can cause water condensation, therefore appropriate insulation must be used. For buildings with more than two storeys and when crossing fire protection walls, the construction of these ducts must prevent fire and smoke from penetrating other fire protection zones (their components must have a fire resistance rating of >90 minutes (F90)). See also national building law. If the external air supply duct has a separate flap for closing, the position of this flap must be recognizable. It must be ensured, that the external air supply flap is open until the fire is burning. Air suction grilles or flaps cannot narrow the free cross section. 2017 Brunner GmbH General Indications Installation of a Brunner fireplace 5
Remember about noise protection! 4 REQUIREMENTS FOR LOCATION Possible locations for a wood-burning stove or fireplace are only such rooms, where no danger can occur, if only the instructions for use are being followed and the system is properly used. The state, structure and intended use of the room must be considered, when choosing the location. Please consider the massive weight of the system. If the floor is not strong enough to bear such load, it has to be distributed by suitable means. A heating device may not be located in the following rooms: 1. Where sufficient volume of combustion air is not guaranteed. 2. Where flammable materials or explosives are stored, manufactured or processed. 3. Which are commonly accessible. Stairways in residential buildings with access from only two flats are not considered as commonly accessible rooms. 4. Where exhaust fans of ventilation or air heating systems are running, unless safe operation of the fireplace is ensured. This is ensured, when: - The systems are causing only circulation of air within the room. - The systems are equipped with safety devices, which automatically and securely prevent negative pressure in this room. - If simultaneous operation of fireplace and ventilation systems is prevented by safety devices. - If the total negative pressure level caused by the stream of combustion air of the fireplace and the airflow volume of the ventilation systems in this room and other rooms included in one ventilation system does not exceed 0.04 mbar. This must be ensured even if easily accessible controls of the ventilation system are being manipulated or removed. - If exhaust gas flow is being monitored by special safety devices. - If the construction type or dimensioning of the systems are excluding the possibility of dangerous negative pressure. Please consult the location of your fireplace, chimney connection and combustion air supply with your local chimney sweep. 6 General Indications Installation of a Brunner fireplace 2017 Brunner GmbH

6 CONNECTIONS AND ASSEMBLY Heating flue / smoke pipe connecting piece Heating gas pipe (21) between heating device and downstream heat radiator or storage mass, as well as the smoke pipe connecting piece (39) connected to chimney must be made of heat-resistant steel with CE mark. The connecting pipe must be connected directly to the chimney. When the connecting piece is leading through structures made of flammable materials, like protected walls (34), then the connecting piece must be insulated to specified thickness, and additionally, the surrounding area of about 20 cm around this insulated piece must be protected by mineral, non-flammable building material (40). The connecting piece must be also insulated in the area of active back ventilation with suitable insulation material to at least 3 cm thickness. In the chimney entrance area it is necessary to provide an opening for measurements and revision. All smoke pipe connections must be sealed tightly! Outside air duct / combustion air pipe If external combustion air supply is necessary, it must be connected directly to the air connecting piece of the heating device, to prevent possible drafts. The combustion air duct must have sufficient cross-section. It must be laid using the shortest way and without unnecessary bends to reduce flow resistance. Combustion air duct dimensioning must be according to EN13884; flow resistance has to be estimated by calculation and must be taken into account! Components of combustion air duct must be made of non-flammable, dimensionally stable and abrasion resistant materials (DIN 4102 A1 or Class A1(B2) according to DIN EN 13501-1); they must ensure tightness und be accessible for inspection and cleaning. Thermal insulation is necessary from the fire-protection point of view, if air temperatures above 85 C (185 F) are possible. Temperatures below dew point can cause water condensation, therefore appropriate insulation must be used. For buildings with more than two storeys and when crossing fire protection walls, the structure of these venting lines must prevent fire and smoke from penetrating other fire protection zones (see regional building law). If the outside air duct has a separate flap for closing, the position of this flap must be recognizable. It must be ensured, that the outside air flap is open until the fire is burning. Air suction grilles or flaps cannot narrow the free cross section. Convection space The stove/fireplace insert must be surrounded by convection space (31/36). When the room air is streaming through the convection space, the heat being set free during combustion is led away into the room. The convection space must be insulated against all surfaces, which are not parts of heat projecting walls of the fireplace. Insulation thickness: see technical data. The convection space is the distance between the fireplace insert and heat insulation and/or outside walls of the fireplace. Convection air routing / Heating chamber / Mounting surface The fireplace, i.e. the heating insert and the additional reheating device (if present) with the heating gas pipe and connecting piece, is enclosed by an external casing or trim, which has to be assembled on site. The external casing consists of walls, bottom plate and top cover, which together form the so called heating chamber. Appropriate external casing materials -> see TROL. Building surfaces can form parts of the external casing (mounting surfaces = e.g. floor area, ceiling area; adjacent wall = part of building wall which is in direct contact with the fireplace casing). 12 General Indications Installation of a Brunner fireplace 2017 Brunner GmbH
The heating chamber must be insulated from all mounting surfaces and adjacent walls (inactive casing surfaces). The necessary insulation thickness depends on the material of mounting surface and the mounting conditions (see "Building protection"). The distances between the stove components and the external casing create a convection space (31/36). Stream of air in this convection space helps to transfer some of the heat which is produced during combustion through the openings in external casing (circulating air/warm air) to the room of installation. Convection casing The convection casing (optional accessory) encloses the significant part of the heating insert and helps to transfer the most of hot air which is produced during combustion. Connections on the top of convection casing allow for transfer of this hot air by using dedicated air ducts. The convection casing does not include the hot air share produced by heating gas pipe, reheating systems and smoke pipe connecting piece. Convection air ducts/shafts All convection air ducts/shafts must be made of abrasion resistant, dimensionally stable and non-flammable materials; they must be tight and accessible for inspection and cleaning. Ducts and duct sections within the fireplace must be executed according to TROL specifications. Appropriate insulation must be provided where necessary. Construction law requirements regarding fire protection must be observed. External casing / Active trim The external casing (37) of the stove/fireplace insert is used to project heat into the room and must be made of non-flammable A1 class building materials according to DIN EN 13501-1. The casing must be stable for a lifetime of the fireplace. Vertical and inclined surfaces of the stove casing, made of mineral building materials, must not exceed 120 C (248#) (surface temperature). Surfaces of the casing, where objects of any kind may be placed for decoration or where wood is held (wood stack), as well as casing walls made of other materials, cannot exceed 85 C (185#) (surface temperature). Use thermal insulation, if necessary. The casing cannot be affixed at any point to the fireplace itself. Its construction must be self-supporting. Between the stove/fireplace insert and the external casing, as well as between the supporting frame and the casing, an expansion strap and/or sealing tape must be used to compensate the different expansions caused by high temperature. Convection air supply Hot air convection system: Fireplace with openings and/or warm air gratings in external casing Without convection casing Room air (circulating air) enters at the bottom of fireplace into the heating chamber (42), it gets warm and returns to the room as convection air through the openings (41) provided in the upper part of the fireplace external casing. The necessary free cross section of the circulation air opening (42) and supply air opening (41) depends on the type of the additional reheating surface and mode of operation (see "Technical data"). Necessary insulation thickness for adjacent wall -> see Building protection. With convection casing Room air (circulating air) enters at the bottom of fireplace into the heating chamber (42). The hot air produced inside the convection casing must be returned through dedicated openings. The hot air can be transferred by ducts or shafts, which are connected at the convection casing outlets. The remaining heat produced by reheating systems, heating gas pipe, and smoke pipe connecting piece must be returned to the room through the openings (41) in the upper part of the external casing. The necessary free cross section of the circulation air opening (42) and warm air opening (41) depends on the type of the additional reheating surface and mode of operation (see "Technical data"). With convection casing, the adjacent wall insulation can be different than specified (see Assembly Instructions for convection casing). Fireplace without openings and/or warm air gratings in external casing (hypocaust principle) 2017 Brunner GmbH General Indications Installation of a Brunner fireplace 13
Convection air is circulating inside a closed fireplace casing. Heat is projected through "active" walls of the fireplace. Thermal load is higher as when heat is returned into the room through warm air openings. This higher load must be taken into account by using appropriate additional thermal insulation (see "Technical data" or e.g. active air cooling). The dimensions and design of active trim must be adapted to the heating power of the heating device. 7 BUILDING PROTECTION All building areas and (adjacent) walls which are in contact with the heating chamber must be protected against overheating. Fire protection and static considerations must be taken into account. From a static point of view, the admissible temperatures must be lower than specified by fire protection requirements. Adjacent walls cannot be exposed to temperatures above 85 C (fire protection requirement). The same is valid for built-in furniture. Required insulation measures depend on the type and design of the surface. The load bearing capacity of the mounting surface must be checked; appropriate means for load distribution must be taken if necessary. Heat insulation Heat insulation layers (32/44/46) must be laid smoothly and overlapping. The surface must be clean and resistant to abrasion. Their planned position must be permanently stable and durable. Insulation layers from abrasive materials must have an appropriate covering (for example, using steel panels). Only approved insulation materials must be used (see "Approved insulation materials"). The insulation thicknesses specified in Technical Data for flammable materials or other materials including flammable components are valid only for components with a heat transfer coefficient (U value) 0,4W/m²K. For U value < 0,4W/m²K, additional measures for thermal insulation must be taken (see DIN 18896:2013-12). Protection of building walls There are two types of building walls: "protected walls" and (other) "adjacent walls". For protected walls, a thermal insulation layer (32) and a brick lining (33) must be used. The brick lining must reach up to the insulation of ceiling or to the height of external casing, and must extend at least 20 cm (7.87 in) above the smoke pipe connecting piece (39). - protected walls are Walls from flammable materials or containing flammable materials, and all walls with flammable objects behind them (e.g. built-in furniture, wooden panels). - other walls (35), these are: Walls from mineral building materials, such as aerated concrete, bricks, sandlime bricks, with thickness of more than 10 cm (3.94 in). For these walls, the insulation layer (32) is enough; a brick lining (33) is not necessary. Protection of ceiling above the fireplace If the stove casing reaches up to the ceiling (43), it must be protected by a sufficient insulation layer (44), if only the ceiling is made from flammable materials or includes supporting elements of the building structure. Floor protection Floors without sufficient load distribution must be provided with a reinforced concrete slab (45) of at least 6 cm (2.36 in) thickness. The mounting surface must be protected against excessive temperatures by sufficient insulation layer (46). 14 General Indications Installation of a Brunner fireplace 2017 Brunner GmbH
Firewood storage The surface temperature of the walls surrounding a recessed firewood storage must not exceed 85 C. This must be ensured by appropriate construction or insulation of walls. Warm air vents/gratings Warm air vents (41) must be situated at least 50 cm (19.69 in) below ceiling level and 30 cm (11.81 in) away from lateral built-in furniture, flammable materials or supporting concrete walls. Air gratings or vents must be located possibly high, to prevent heat accumulation within the external fireplace casing. Air gratings or vents must allow for easy cleaning. The required unobstructed area of air gratings depends on the type of reheating device. The air gratings or air vents must be arranged to avoid clogging up. Active air cooling Active air cooling is a permanently open, non-closing shaft, gap or empty space, where part of the heat projected by the fireplace is dissipated by convection to protect the building or flammable components in adjacent walls or mounting surface. Decorative beam over fireplace door Decorative beams (52) are allowed with 1 cm clearance between the beam and the wall of the fireplace casing (37), only outside the heat radiation range. The clearance must not allow for heat accumulation between the beam and the fireplace wall. Decorative beams cannot be parts of the building structure. Floor before fireplace door Floors from flammable materials must be protected by a cover (47) from non-flammable materials or replaced by non-flammable materials with the following dimensions: - in front of the fireplace = at least 50 cm (19.69 in) - on both sides of the fireplace = at least 30 cm (11.81 in) above the fireplace door opening Within heat radiation range of the fireplace Structures from flammable building materials or including flammable components (48), as well as built-in furniture (49) must be separated from the combustion chamber opening in front, to the sides and above the fireplace by at least 80 cm air clearance. If these parts are protected by a heat protecting screen cooled by air on both sides, a distance of 40 cm must be kept. Outside the heat radiation range Structures from flammable materials (48) or with flammable components, as well as built-in furniture (49) must have at least 5 cm air clearance to the outside walls of the fireplace. In this clearance, the room air must be able to circulate without any obstacles. Heat accumulation must be avoided. Structures covering only small areas of the fireplace casing walls, like flooring, adjoining wall coverings and insulation layers on ceiling and building walls, can be led right up to the fireplace casing. 2017 Brunner GmbH General Indications Installation of a Brunner fireplace 15
Electric lines Mounting surface must be free from typical electrical wiring, unless it is protected by special measures against permanent influence of temperatures >30 C (86 F). Special wiring with higher heat resistance is permitted (see TROL). 8 CHIMNEY AND SMOKE PIPE CONNECTION Chimney and smoke pipe connection design must be in accordance with DIN 18160.1 or DIN EN 15287-1; dimensions must be calculated according to DIN EN 13384. Connection of multiple fireplaces to the same chimney is possible, when it can be proven that the chimney is suitable, even if the design of these fireplaces is different (calculation of flow and thermal balance and approval from chimney sweep are necessary). However, it is not possible for fireplaces designed for open door use. Remember to use a separate chimney connection in this case. If the connecting pipe between additional reheating devices (radiators, storage mass) and chimney is a steel flue gas pipe, it must be suitable for this application, it must conform to DIN EN 1856-2 standard and have a CE mark. The connecting pipe must be connected directly to the chimney. A soot fire resistant chimney of T400 type is necessary for safe operation. All smoke pipe connections must be sealed tightly! Remember to provide access for cleaning! 16 General Indications Installation of a Brunner fireplace 2017 Brunner GmbH
9 MOUNTING INSTRUCTIONS FOR EAS / EOS VARIANTS Illustr. 1: Schematic layout of EAS Illustr. 2: Schematic layout of EOS The indicated temperatures are maximal permissible temperatures of components! The indicated cable dimensions are minimal dimensions! Installation of electronic components must be prepared and performed carefully. Please pay attention to the following points: The flush-mounting box must be fitted in level and clean, to ensure easy, tension-free installation of electronics. Prevent any physical contact with electronic components - possible electrostatic discharge can damage them. Humidity can affect electronic components. Therefore, it is very important to ensure clean and dry installation of electronics. If possible, avoid installation of electronic components in exterior walls to prevent risk of corrosion at temperatures below dew point. The control unit must not be installed in hot parts of the tiled stove casing. 2017 Brunner GmbH General Indications Installation of a Brunner fireplace 17
The selected type of installation must ensure that temperatures do not exceed +40# (140 F) and the unit is not exposed to direct heat radiation. For units with external air supply, the motorized combustion air flap assembly cannot be installed in such way that the motor is located under the flap. Condensate could penetrate the motor and destroy it. To avoid risk of damage, all cable conduits leading from electronics into the heating chamber must enter at the bottom of the stove casing. Cable conduits cannot end in upper parts of the heating chamber due to excessive temperature. All electronic components must be accessible after installation for revision and replacement. When selecting place of installation, keep in mind the max. permitted temperature for the component. Components cannot be installed in closed spaces; proper ventilation must ensure sufficient heat discharge. 18 General Indications Installation of a Brunner fireplace 2017 Brunner GmbH
10 APPROVED INSULATION MATERIALS Thermal insulation materials used must fulfil the following requirements according to AGI-Q 132 standard: Material: Group 12, 13 Rock wool or slag wool Delivered as: Group 06, 07, 08 slabs, stitched mats or shells Thermal conductivity: Group 01-21 Upper temperature limit: Group 70-76 equivalent to 700 o C - 760 o C Nominal density kg/m 3 : Group 08-18 equivalent to 80 kg/m 3-180 kg/m 3 Thermal insulation materials used must be at least equivalent to class A1 building materials according to DIN 4102, Part 1.
